AUTOMATIC CLOSER FOR POWDER-BECEPTACLES.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed March 14, 1908. Serial No. 421,028.

' Closers for Powder-Receptacles, of which the following is a specification.

My invention relates to new and useful 1mrovements in automatic closers for cans,

ottles, and the like, and has for its object to provide an exceedingly sim is and eiiective device by which cans for iolding toothpowder and the like will be automatically closed, While readily permitting the Withdrawal of a small quantity of the powder when desired.-.

With these ends inview, this invention consists in the details of construction and combination of elements hereinafter set forth and then designated by the claims.

The construction and mode of operation will be understood by referring to the accompanying drawing, in which like figures of reference designate similar parts.

' Figure 1 is a side elevation of a toothpowder can having my invention ap lied thereto. improvement. Fig. 3 is a view similar to Fig. 2, showing the cap deflected to allow the removal of' owder. Fig. 4 is a section on line.A-A -o Fig.2 illustrating the ivots of the movable cap. Fig. 5 is a 1110Cl1 ed construction.

- Referring to the accompanying drawing, 1 represents a can containing tooth-powder or the like, 2 is a. cover which fits over and is secured to one end of the can. In the center of this cover is formed a spherical head 3 projecting outward and,preferably made integral with the cover through the neck 4. In

. the'extreme top of the head 3 is formed the slot 5 and in one side the opening 6, the purpose of which will hereinafter ap ear. portion of metal 7 is cut from the s 0t 5 and ent downwardly, as shown in Figs.2 and 3. In this in whic over the head 3 is a hemi-spherica cap 9. On this cap 9 is formed the ball or handle 10 which is made by stam ing and rolling up a stri of metal from whic the cap 9 is formed. In t -'s cap 9 is also formed a slight indentation 11, and on the sides are formed ears 12 and 13. A spring'lt of suitable strength is used to keep the cap 9 in a po'sition over the Fig. 2 is-a vertical section 0 my 1piece of metal 7 is formed the hole. 8

engages spring 14. Fittin snugly opening 6, one end of this spring is bent at right angles and inserted in the opening 8.111 the iece 7. The 0 'posite end projects upwardly through thes 0t 5. The cap 9 is then placed in position, the free end of the spring resting in the indentation 11. The cap 9 is pressed down snug upon the. head 3 with the cars 12 and 13 on sides at right angles to the opening 6. Pivots are then formed by indenting the ears as shown at 15 and 16 in Fig. 4, thus fastening and pivoting the cap securely to the head 3.

When it is desired to withdraw powder the box is gras edin the hand and the ba 10 is pressed Back .by the forefinger thus swinging back the cap 9 on the pivots 15 and 16 until the opening 6 is uncovered and the s ring is put under tension. The box is t en tipped until powder flows out through the opening 6. By releasing the ball 10 t e spring carries the cap back to its former p0- sltion cutting oil the flow of the powder and sealing the box. 7 r In Fig. 5 I have shown amodifiedconstruction in which a partially cylindrical head 17 and cap 18 are used, and in which I have also indicated screw threads 19 so that the cover may be placed upon a bottle or the like. In other particulars, the construction and operation are the same as before described.

- /Vhat I claim is:

1. In a device of the character described, the combination with a curved head having a discharge aperture, of a similarly shaped aperture closing .cap embracing said head outside thereofand pivoted thereto, a slot in said head, and a spring assmg through said slot and enga ing said ead and ca 2. In a device 0 the character descri ed, the combination with a curved head havin a dischar e aperture, of a similarly shape aperture 0 osing cap embracing said head and A. movable thereon to open and close said aperture, a slot in said head, and a spring connected to said head and extending through said slot and enga i said ca 3. In a device (Fi th p the combination with a curved head havin a discharge aperture, of a similarlg shape aperture closing cap embracing an pivoted to said head a slot in said head extending at right angles to the pivotal axis of sai cap, and a spring assin through said slot and connecting sai bee and cap.
